TELEPHGNE APPARATUS.

Specification of Letters Patent.

Patented July 28, 1908.

Application filed November 4, 1907. Serial No. 4590334.

comprising a transmitter and receiver or re' ceivers adapted to be secured to the head of the user'so'that the receiver or receivers and transmitter are always maintained in proper relation with the ears and mouth regardless of the movement of the body and head of the user, whereby the user is able to move about from place to place and move his head from side to side Without moving his mouth and ears out of proper relation with the transmitter and receivers.

The object is further to provide an appara tus of the character described which is adjustable to heads of various sizes and shapes, adjusted and which will be comfortable to the user.

While the apparatus of my invention is obviously capable of being used for various purposes, it is particularly adapted for use on war vessels to establish communication between the range finding officer and the gun captain.

Other objects and advantages will appear hereinafter.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in. the appendcd claims.

Referring to the drmvings: Figure 1 is a plan of my improved telephone apparatus shown partly in section. Fig. 2 is an enlarged sectional ele 'ation taken on line 22 of Fig.

.1. Fig. 3 is an enlarged dctail front elevation of the transmitter and a portion of the transmitter support showing the method of securingsaid transmitter to said support. Fig. 4 is Si side elevation of my apparatus as applied. to thehead of the user, the head. being indicated in dotted lines. Fig. 5 is an enlarged detail sectional elevation taken online of Fig. 1, looking toward the right.

Like numerals refer to like parts throughout the several views of the drawings In the drawings, 10, are two members preferably formed of leather or other suitable flexible material and provided, respectively,

in posts or studs 31 31,

With holes 11, 11. Two members 12, 12 pro Vided, respectively, with holes 13, 13 are also preferably formed of flexible material such as leather and secured to the members 10, 10, respectively, by stitching 14, 14 extending around said members adjacent to the periph ery thereof. Two receivers 15, 15 extend through the holes 13, 13, respectively, said receivers being provided, respectively, with annular flanges 16, 16 locatcd between the members 10 and 12. A strap 17 adapted to extend over the top of the users head is formed in two parts 18, 1S adiustahly connected to each otherl means of a buckle 1S said parts being secured to the incmbcrs 10 and 12 by being inserted thcrcbctwccn and held in place by mcans of the stitching l-l. Similarly, a strap 20 adapted to cxtcnd around the back of the head formed in two parts 2]., 21 adjustably conncctcd .to cach other by means of a buckle 22, the ends of said stray being introduccd between the members 10 and 12 and secured thcrcto by the stitching H.

Twostraps 2;, 23 adapted to extcnd bcneaih the chin are also inserted between the members 10 and i2 and held in place by the. stitching 14, said straps being: adjustably se cured to each other, as by tying together in a bow knot,-as shown? By adjusting the straps 17, 20 and the head piece of which they form a part. maybe adapted to various sizes and shapes of heads. .& transmitter 2i mounted on a transmitter support 25 may be a'djustably secured thereto by means of two screws 26, 26 havingscrcu threzuicd cngagcment therewith, said screws cxicnding' through a clamping plate 27 and passing through a slot 28 formed in the transmitter suppcrt 25, whcrcl'iy said transmitter maybe. adiusted longit udinully of said slot.

The transmitter support 25 may be adjustably connected to the members 12, 12 by connections which I will now proceed to describe.

The transmitter support 25 which is pref erably U-shaped as shown, is provided with two arms 29, 29 located in holes 30, 3t) formed respectively, said studs being mounted, respectively, on brackets or plates 32, 32 by means of screws 33, 33 which are rigidly secured to said brackets, rospectively, and which pass through said studs and through slots 34, 34 formed in the. arms 29, 29, respectively. "iwo thumb-nuts 35, 35 having" screw-threadedengagement with the screws 33, 33, respectively, are adapted to clamp the arms 29, 29, respectively, in the studs 31, 31 respectively, and also clamp said studs against the plates 32, 32, respectively, thus preventing said studs from rotating on the screws 33, 33. The plates 32, 32 may be secured to the members 12, 12, respectively, in any desired manner as, for instance, by splitting the free ends of said plates thus forming on each of said free ends two arms 36 and 37, the arms 36 being bent as shown so that the edgeof the member 12 adjacent to the hole 13 may be introduced between the arms 36 and 37, as clearly shown in Figs. 2 and 5. The leather forming the member 12 by reason of this peculiar engagement with the arms 36 and 37 prevents the plate 32 from rotating with relation to the member 12. Set screws 38, 38 having screwthreaded engagement with the plates 32, 32 bear against the receivers 15, 15 and clamp said plates to said receivers, respectively. The receivers 15, 15 and the transmitter 24 may be connectedby any usual or desired wiring, not shown. It will be seen that the transmitter 24 may be adjusted toward and away from the mouth of the user by loosening the nuts 35, 35 and sliding the arms'29, 29 in the posts or studs 31 31 respectively, and said transmitter may also be adjusted vertically with relation to the mouth by rocking the support 25 on the axis of the screws 33, 33, whereby the studs 31 31 are rocked on said screws. When the transmitter 24 is thus properly adjusted it is then rigidly clamped by rotating the thumb-nuts 35, 35 in the proper direction to clamp the arms 29, 29 in the studs 31, 31, respectively, and clamp said studs against the plates 32, 32 respectively. It will be also evident that when the user wishes to move the transmitter 24 entirely out of the way he can by loosening the nuts 35, 35 swing said transmitter and its support 25 into the position shown in broken lines, Fig. 4, in which position it may be rigidly clamped as hereinbefore described.
